WINDIVHLL.

SPECIFICATION forming part of Letters Patent No. 390,517, dated October2, 1888.

Application filed November 1S, ISST. Scl-inl No. 255,516. (No model.)

To aZ whom t may concern:

Be it known that I, GUsTAvUs A.. RAAseH, of Higginsville, in the countyof La Fayette and State of Missouri, have invented certain new anduseful Improvements in W'indmills; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it pertains to make anduse it, reference being had to the accompanying drawings, which formpart of this specification.

My invention relates to an improvement in windmills; and it consists inthe arrangement and combination of devices, which will be more fullydescribed hereinafter, whereby an automatically regulating windmill isproduced.

Figure I is a side elevation of a windmill embodying my invention,partly in section. Figs. 2 and 3 are detail views of the same.

A represents a portion of the frame-work which forms a bearing for theshaft B. In the top of this frame A is formed a suitable oil-well, C, inwhich the lubricant is placed, and in which the disks D, secured to theshaft B, revolve. As these disks revolve, they catch the oil in the wellC and feed it to bearings E -upon each side of the disks, so as to keepthe shaft constantly lubricated. Secured to the shaft is the hub F,which is curved backward over the shaft, as shown, and to which thevanes of the wheel are secured by means of the ring G, which is clampedto the hub F by suitable bolts in such a manner as to hold the innerends of the vanes rigidly in position. Both the inn'er side of thevertical part of the hub F and the inner side of the ring G are madecorrugated, so as to take a firm hold upon the vanes, and thus preventany possibility of their working loose. The hub F is shaped, as shown,so as to bring the weight of the wheel back over the front bearing, andthus balance the Wheel in position, instead of securing the wheel to theend of the shaft in the usual manner.

To the inner end of the shaft B is secured the disk H, from whichextends the wrist-pin, and upon this Wrist-pin is placed thefrictionroller I. This frictionroller is held, as the disk H revolves,in the vertically moving frame J, which is provided with ilanges K,which catch over opposite sides of the edges of the wheel I, and thusprevent it from getting out of line with the frame or becoming displacedtherefrom. This frame .I is composed of two parts which are boltedtogether and which must be separated before the frietion-roller can beremoved. The dauges K upon the lower part of the frame J serve to hold asuitable quantity of oil, in which the roller I revolves, so as to keepthe roller always lubricated and to cause it to work with as littlefriction as possible. This verticallymoving frame J is held betweensuitableguides formed upon the frame A, and to this frame the pitman issecured. Projecting at right angles to inner end of the frame A is thearm L, by means of which the frame A is swung around, so as to presentthe wheel either at au angle or with its edge to the wind.

The beam M, to which the vane is secured, is pivoted to the frame A, andmounted upon this beam M is the support N, upon which the weighted leverO is pivoted. The upper end of this lever O is provided with an eye, inwhich the operating wire, rope, or chain is fastened for the purpose ofmoving the wheel out of the wind. The weight P on the lower end of thelever O is vertically adjustable, so as to increase or decrease theamount of power which is required to remove the lever. Extending fromthis lever O is a connectingrod, Q, which has its front end fastened tothe arm L, and by means of which the wheel is swung around, so as topresent its edge to the wiud. Also fastened to this lever O is aconnecting rod, R, which has its rear end fastened to the arm S, whichprojects at a suitable angle from the weighted lever T, which isprovided with a vane, U, at its upper end and an adjustable weight, V,at its lower one. 'When the lever O has its upper end drawn downward bythe wire or cord connected thereto, a pull is eX- erted upon the frameA, so as to swing the wheel around with its edge to the wind, and at thesame time a push is exerted upon the lever T, so as to force itbackward, as shown in dotted lines. In case ofa storm the pressure ofthe wind against the vane U forces the lever T backward, and then therod R exerts IOO a Apull both upon the lever O -and the frame A', so asto swing the Wheel around. The two Weights V P serve to return the partsquickly to position as soon as they are left free to move either by theslackening of the cord or Wire or the lessening in the force of thewind.

Having thus described my invention, I claim- The combination of theframe A, provided with a projection, L, upon one side, the shrtft 3,journaled in the frame and having the Wind wheel secu red thereto, withthe main frame M, pivoted to the frame A,thesupport N, mounted upon thebeam, the Weighted lever O, journnled or pivoted upon the support, theWeighted :5 lever T, pivoted upon the beam and provided with the Vane Uat its upper end and the arm S, the connecting-rod R, which connects thetwo Weighted levers together, and the rod Q, which connects the lever Owith the projection zo L upon the frame, substantially as set forth.

In testimony whereof I affix my signature in presence of tWo Witnesses.
